I see a lot of functions are meant for char's and not strings. FOr example, isalpha().
In my case I want to use isalpha but I have a string. The good news is it's a single digit string using substr to grab each individually.
I want to cast my (val.substr(1,1) into a char for isalpha to process. Everythign I read says string to char is a no-no.
Ideas?
